MIT Scientists Design Vehicle That Folds At The Press Of A Button Cambridge (Massachusetts):Wouldn't it be nice to drive a car into town without worrying about finding a parking space? Scientists at the Massachusetts Institute of Technology have devised just such a vehicle, a futuristic "City Car' that could even drive itself. Once at your destination, the vehicle's computers would, at the press of a button, look for a parking spot behind others like itself, then fold roughly in half so you could stack it there as you would a shopping cart. "We have reinvented urban mobility,' said Bill Mitchell, a professor in architecture and director of the project at an MIT think tank in Cambridge, just outside Boston. The vehicle hasn't yet been built. But a miniature mock-up version has gone on display at a campus museum, and there are plans to build a full-scale model this spring. The dozen or so engineers and architects on Mitchell's team are confident their computer-generated work is on target. They feel their golf cart-sized vehicle could provide a novel solution to the chronic traffic congestion afflicting cities across the United States, Europe and Asia
